So I've had my baby Red Tail for a few weeks now. I've noticed when I handle him, the underside of his mouth puffs up and he makes slight hissing/popping noises. I've read on different accounts that boas tend to be loud breathers, although I'm not necessarily believing it. My gut along with what I have read about RI's tell me this is actually a sign of an RI. I have checked his mouth, and there isn't any excessive mucus/bubbling. I have never had a first hand experience with an RI from my other snakes, so I wanted to see what you guys think. Thank you!
